SHIP const rnuc rron.
Application filed October 26, 1922. Serial No. 596,981.
T 0 all whomz't may concern:
Be it known that I, JOSEPH T. L. LAvA- on'r'ro, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Ship Construction, of which the following is a specification.
My inventlon relates to improvements in which the outer planking is seated in metal ribs, and in which the oakum is held in a longitudinal groove in the long edge of the plank.
The objects of my invention are First, to strengthen the hull by means of metal ribs.
Second, to afford superior protection against damage.
Third, to make provisions for easy replace-' ment of damaged planks.
Fourth, to provide means for retaining the oakum in the seams.
Further objects and advantages will be found in the specifications and particularly 7 pointed out in the appended claims.
I attain these objects with the mechanism illustrated in the accompanying drawing, in which p Fig. 1 is an elevation ofa ships hull.
Fig. 2 is a detail of the metal rib.
Fig. 3 shows the oakum between two planks.
Similar numerals refer to similar parts throughout the several views. I
The Wooden rib 1 of the frame work is first covered with the customary planks 2. On top of these planks is placed a metal rib Whose bottom flange 3 reposes in a. groove in the planks 2 to be flush with the outer surface. A bolt 4 holds the metal rib tothe wooden rib. From the web 5 of the metal rib extends a top flange 6 in the direction of the stern of the ship so that "in case of collision the force of the impact is taken up rather by the stronger web than by the weaker edge of the top flange. The channel formed by the top and bottom flanges is utilized to hold one end 7 of the outer or cover plank 8, the other end 9 of the same plank is fitted into the angle between the bottom flange and web of the adjacent metal rib and securely held in place by a lag screw 10. Oakum 11 is calked into the joint wherethe end 9 abuts the web 5. In case of repair it is thus an easy matter to remove the damaged plank and insert a new one. I
The outer planks 8 are further provided with a groove in one edge for the reception of a strand of oakum 12 (Fig. 3).
strand should be thick enough to fill the jointcompletely when two planks are pressedtogether. A loss of the oakum is thereby absolutely avoided.
The
A copper sheathing 13, covering the hull below the water line protects the wood work against damage by teredos, barnacles and copper sheathing should extend to the anchor hole 14, so that the planks will not be marred other subaquatic animals. .The
by the anchor.
Having thus described invention it will be-seen that my objects have been'ac-,.
complished, and, though I have shown the preferred form of construction, I reserve to myself the right to make minor changes providing I do not violate the spirit and principle of my invention. v
I claim:
prising wooden ribs, inner planks secured on the wooden ribs, metal ribson the outer surface of the inner planks adapted .to form a seat for the outer planks, and outer planks having one edge grooved for the reception 7 of oakum.
2. A copper sheathed woodenhull, coniprising wooden ribs, a double- 12 er of .1. A copper sheathed wooden hull, com

flange.
planks having one edge grooved for the reception of oakum, and metal ribs holding copper sheathed wooden hull com- 1 prising w'ooden ribs, a double layer of said planks to the wooden ribs, said'metal ribs includinga bottom flange, a web atqthe center line of the bottom flange,and a topflange extending from the web toward one side.
5. A copper sheathed wooden, hull, comprising metal ribs, having a bottom flange,
a Web, a top flange extending at right angles the outside of the Wooden ribs, a double layer from the Web toward the stern,-and planks of planks held in place by the Wooden and having one end held between the top and metal ribs, and a longitudinal groove in bottom flange and the other end reposing in the long edge of each plank for the recep- 5 the corner formed by the bottom flange and tion of oakum; Web of the adjoining metal rib. Signed by me at Portland, Ore, this 21st 6. A copper sheathed Wooden hull, comday of October, 1922; prising wooden ribs, metal ribs attached to J. T. L. LAVAGETTO.
